一种基于数据动态迁移的分级备份系统的研究

摘要

随着运营商信息化进程的不断深化，业务数据量处于高速的增长，管理信息系统的高效访问以及安全性正在变得越来越重要。本文以信息系统的数据价值评估为基础，提出一种数据动态迁移模型，并引入虚拟带库作为近线存储，形成完整的解决方案。实现传统备份到分级备份的升级改造，优化信息系统备份架构，提高数据的访问以及保护的效率。%With rapid development of informatization advancement and steep rise of total quantity of data,security and reliability of information system become more and more important.This paper introduced a dynamic migratory pattern based on dynamic value evaluation,and put forward a solution using virtual library as near-line storage.The solution optimizes the framework of backup,and the measurement indicates that the security and reliability of information system has been boos-ted.
